Scientists found that when packaged in a nanoparticle, CT contrast agents, such as iodine, increased the absorption of X-rays by nearly an order of magnitude, thus improving sensitivity for imaging and disease characterization and potentially reducing toxicity compared with conventional contrast agents.
Researchers have shown for the first time that fluorescent nanoparticles placed near a mirror generate unique patterns that can be used to pinpoint their location.
Classical motors convert a form of energy such as heat into mechanical work. Can these laws also be transferred to a miniature machine that consists of only a single cesium atom and could thus work more efficiently? Physicists now have provided the proof.
Scientists ventured to modify Pauling's formula and redefine the electronegativities of elements and ended up creating a new scale of electronegativity.
